Provision of information from firms, firm establishments, municipal administrations, scientific institutes, foundations, ministries and other organizations and departments which during the year under review have spent expenditure on protection and restoration of the environment. Included here is the expenditure on acquisition as well as the expenditure on maintenance of the tangible fixed assets with ecological use allocated by direction of ecological use (water, air, waste, etc.).
· Classification of environmental protection activities (CEPA)- a common classification of environmental protection activities which has been adopted by UN and European statisticians and accountants in 1994 and replaced in 2000 by an improved version (CEPA 2000);
· Nomenclature of environmental protection equipment.
Included are the economic subjects from all economic sectors, which have spent environmental protection expenditure.
|Statistical concepts and definitions|
Specialized equipment for the environment (end-of-pipe) - includes facilities which are not involved in the production process and serve only to reduce pollution resulting from production.
Integrated technologies - elements of the production process/technologies, which resulted in achieving less environmental pollution compared to other similar technologies.
Economic units that have spent funds for new construction, reconstruction, maintenance and operation of tangible and intangible fixed assets and activities on the environment.
All economic units that have expended funds for the acquisition and maintenance of tangible and intangible fixed assets with ecological use.
The data for enterprises and the number of employed persons from the Statistical Business Register for the period t-2 were used to form the general population, from which the study "Expenditures for protection and restoration of the environment" is sampled. For the study of the group, two approaches are combined - exhaustive and sampling. Comprehensive monitoring applies to a group of enterprises that are previously known to have environmental expenditure, and where the industry group surveyed contains too few enterprises to be sampled.
By regulation, data are reported by economic activity group. For each sample, a simple random sample is emitted.
Based on the sampling survey, estimates are calculated for the enterprise's arithmetic mean for the sampled population. In order to obtain an estimate of the aggregate, the arithmetic mean is multiplied by the number of enterprises.
Total for the country and by districts - 2000-2013. Begining 2014 only total for the country.
2000 - 2020
Expenditure on protection and restoration of the environment are included economic subjects (companies, organizations, ministries, municipal administrations and others) who have spent funds on protection and restoration of the environment.For the study of the group, two approaches are combined - exhaustive and sampling. Comprehensive monitoring applies to a group of enterprises that are previously known to have environmental expenditure, and where the industry group surveyed contains too few enterprises to be sampled.>
|Frequency of data collection|
The main source of data is a statistical questionnaire on the expenditure for protection and restoration of the environment. The questionnaire is collected by correspondence on electronic and paper format.
Comparing the data with those reported in the previous year for incorrect measure units and incorrect data by use for environment.
Dataset containing all the units in the terrritory of the country.
· European Statistics Code of Practice;
· A common framework for quality management in the National Statistical System.
Main users of survey's statistical information are the state and municipal entities, associations, companies and citizens.
No information. Survey about satisfaction of customers has not been conducted.
According to Regulation 691/2011, all available statistics data are reported. In 2019, progress is being made to ensure the completeness of the missing data. Possibilities for obtaining information for missing statistical indicators are being explored.
|Data completeness - rate|
|Accuracy and reliability|
Overall accuracy is related to data quality. For this purpose , additional analyzes and checks are performed on all economic units that are suspected of having incorrect units of measurement, incorectly indicators and others.
As the sample size depends on the available resources and not on the pre-set accuracy when conducting the study, the calculation of stochastic errors is not part of the usual procedure accompanying data processing.
|Sampling errors - indicators|
|Over-coverage - rate|
|Common units - proportion|
|Non response error|
|Unit non-response - rate|
|Item non-response - rate|
|Imputation - rate|
|Model assumption error|
|Data revision - policy|
Revision of the data is applied if necessary.
|Data revision - practice|
Revision of the data is applied if necessary.
|Data revision - average size|
|Timeliness and punctuality|
The data is published according to the terms laid down in the Release Calendar presenting the results of the statistical surveys carried out by the National Statistical Institute.
|Time lag - first results|
|Time lag - final results|
All publications are prepared timely, according to the Release Calendar presenting the results of the statistical surveys carried out by the National Statistical Institute.

|Coherence and comparability|
|Comparability - geographical|
Due to the unity of principles, variables, definitions and classifications used there is a high degree of comparability between EU Member States with regard to the survey's results.
|Asymmetry for mirror flows statistics - coefficient|
|Comparability - over time|
Time series are available since 2000.
|Length of comparable time series|
|Coherence - cross domain|
|Coherence - sub annual and annual statistics|
|Coherence - National Accounts|
There are data that are according with National Non-Financial Accounts.
|Coherence - internal|
